Soil Cells

RootSpace

The GreenBlue Urban RootSpace® system is essentially a soil support system – designed for maximum soil and rooting volume, to be ‘utility friendly’, with economic freight and industry leading strength characteristics.

In 2001, GreenBlue Urban produced the world’s first purpose made commercial structural soil cell for urban tree planting. Since that time, thousands of trees have benefited and continue to benefit, from access to uncompacted soil volumes – beneath heavily engineered pavements and roadways.

RootSpace® is the next generation soil protection product, developed by GreenBlue Urban to reduce cost, cut down installation time, and incorporate industry leading soil aeration methodology – a vital and often overlooked component in tree pit design.

Features

  • Interlocking System
  • Integrates with other ArborSystem products

Benefits

  • Interlocking recycled material panels give huge strength
  • Open structure – fast filling and class leading soil void ratio – more soil for the tree
  • Fast installation reduces labour costs
  • Less plastic – reduces costs
  • Unique patented Airflow lid – encourages movement of air allowing the soil to breathe
  • Excellent space provision for integrating utilities
  • Lid designed to allow fast re-excavation for utility emergencies
  • Open lattice – high strength but maximum soil space

StrataCell

Representing the fourth-generation of RootCell development, the StrataCell developed in 2007 designed to support highly advanced engineering specifications.

The StrataCell provides a large module with more space for extensive root growth in large-canopy trees, bringing the tree-root system closer to the pavement surface yet still supporting maximum traffic loads.

Features

Working in collaboration with other industry leaders, StrataCell structural soil cell was built upon successful trials and projects that were also aimed at reducing installation and transport costs, and improving the module’s robust strength. Built to advanced engineering specifications to support greater vertical loads, StrataCell brings tree-root systems closer to pavement surfaces. Engineers have calculated that with only 300mm of granular pavement depth, a StrataCell matrix can support maximum pedestrian and sidewalk traffic loads. With vertical and lateral forces also considered in the engineering make-up of tree pits, StrataCell’s well-designed matrix units lock together well, forming a monolithic framework with excellent modular strength. Highly secure connectors allow for StrataCell modules to click together fast and simply. Its open and skeletal structure provides an enormous growth zone for delicate root systems and storm water harvesting, with an excess of 94% of the soil volume allocated for tree-root growth. These high soil-volume tree pits are distinctly more advantageous, as optimum conditions for nature and nurture are recreated for trees to live and flourish. StrataCell apertures are built to generous specifications, permitting common conduits, service pipes and aeration mechanisms to be incorporated into the structure’s design.

Benefits

  • Designed to support enormous vertical as well as lateral loads
  • Excellent modular strength
  • Integrated matrix means modules are simple and fast to click together
  • In excess of 94% of total soil volume is available for tree-root growth
  • Generously designed apertures permit common conduits, service pipes and aeration systems
  • Significant volume reduction for freight and lower transport costs
  • Made from 100% post-industrial waste material

Derry Tree Planting

We have had the pleasure of working with Derry City Council to place new trees around the city centre.
